android - RXJava - onBackpressureBuffer + multiple observers not working -


i have observable , subscribe it. need not miss emitted result, use onbackpressurebuffer following:

observable<data> observable = observable.onbackpressurebuffer(); if (buildconfig.debug) {     observable          .subscribeon(handlerscheduler.from(datamanager.getbackgroundhandler()))         .observeon(handlerscheduler.from(datamanager.getbackgroundhandler()))         .subscribe(new measuringsubscriber(...)); } // here real observer need in app observable         .subscribeon(handlerscheduler.from(datamanager.getbackgroundhandler()))         .observeon(androidschedulers.mainthread())         .subscribe(new observer<data>()         {             @override             public void oncompleted() {              }              @override             public void onerror(throwable e) {              }              @override             public void onnext(data data) {              }         });

the measuringsubscriber custom subscriber logs how long task needs, that's all.

problem

if add measuringsubscriber, subscribers not work anymore , never emit result. why? , how can make working?

edit - new problem

currently it's working, measuringsubscriber somehow blocking, meaning, first items emitted 1 one measuringsubscriber , afterwards items emitted 1 one main subscriber... ideas cause that?

i have solution - can extend main observalbe measuringobservable - rather know why happens , how avoid this...

i tried using publish + connect, still emit items first subscriber before emitting them second one...

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
